Best A-Levels for Studying Medicine: Your Complete Guide to Medical School Success

Are you dreaming of becoming a doctor? If so, choosing the right A-Levels is your first critical step. Getting into medical school is highly competitive, and your A-Level choices can significantly impact your chances of admission. In this article, we’ll explore the best A-Level subjects for studying medicine, how universities evaluate applicants, and what combinations will give you the best shot at success.

Whether you’re studying in the UK, Sri Lanka, or anywhere else under a similar curriculum, this guide will help you make smart decisions for your future in medicine.

Why A-Levels Matter for Medicine

Medical schools receive thousands of applications each year. To shortlist candidates, admissions teams look closely at your academic performance, especially your A-Level results. These subjects form the foundation of your knowledge in core sciences and determine whether you're ready for the rigorous study of medicine.

Core A-Level Subjects Required by Most Medical Schools

Let’s break down the must-have subjects if you’re serious about applying to medicine.

1. Biology – Essential for Medicine

Keyword: A-Levels for Medicine, Biology A-Level for Medical School

Biology is almost always a required subject for medical school applicants. It covers the fundamentals of human anatomy, physiology, genetics, and cellular biology—all crucial topics in medical education.

Most UK universities and international medical schools consider Biology mandatory or strongly preferred.

Why take Biology?

It demonstrates your understanding of living systems, prepares you for topics like pathology and pharmacology, and is essential for nearly all medicine programs.

2. Chemistry – Usually Mandatory

Keyword: Chemistry A-Level Medicine Requirement

Chemistry is another essential A-Level subject for medicine. Many top medical schools, including Oxford and Cambridge, list Chemistry as a strict requirement. This subject provides the foundation for understanding biochemistry, drug mechanisms, and chemical processes in the human body.

Why take Chemistry?

Without Chemistry, your application may not even be considered at many universities. It teaches logical thinking, lab skills, and scientific analysis, which are vital for any future doctor.

Highly Recommended A-Level Subjects for Medicine

Aside from Biology and Chemistry, one more subject is typically needed to complete your trio. Some subjects stand out as more useful than others.

3. Mathematics – Strongly Recommended

While not always compulsory, Mathematics is highly valued. It supports understanding data interpretation, statistics, pharmacokinetics, and logical problem-solving.

Advantages of taking Mathematics:

Enhances your application competitiveness
Complements Chemistry and Biology well
Useful for entrance exams like UCAT and BMAT

4. Physics – A Good Complement

Physics isn’t essential but can be very beneficial, especially for students interested in the scientific and diagnostic side of medicine (e.g., radiology, medical imaging).

Many universities accept Physics in place of Mathematics or as a fourth A-Level.

Advantages of taking Physics:

Demonstrates analytical thinking
Supports biomedical engineering and diagnostic understanding
Shows your comfort with hard sciences

Optional but Acceptable A-Level Subjects

5. Psychology

Psychology can be an interesting third A-Level, especially if you're drawn to psychiatry or behavioral science. It’s usually accepted alongside Chemistry and Biology, though not considered a core science.

6. Further Mathematics

If you are highly proficient in Maths, Further Mathematics shows academic strength. However, don’t take it at the expense of Biology or Chemistry.

7. English or a Modern Language

Although not required, a strong arts or language subject can demonstrate communication skills, essay writing, and critical thinking—skills every doctor needs.

A-Level Combinations That Work Best for Medicine

Keyword: Best A-Level Subject Combinations for Medicine

Here are some top-performing subject combinations for medical school applicants:

Combination 1:

Biology
Chemistry
Mathematics

Widely accepted

Strong scientific foundation

Prepares you for entrance tests

Combination 2:

Biology
Chemistry
Physics

Strong in practical sciences

Helpful for understanding diagnostics

Well-respected combinationCombination 3:

Biology
Chemistry
Psychology

Useful if you're interested in psychiatry

Requires strong justification in personal statement

Subjects to Avoid for Medical School Applications

Some A-Levels are considered less rigorous and may not be viewed favorably by admissions teams.

Avoid or limit:

General Studies
Critical Thinking
Media Studies
Travel and Tourism
PE (unless applying to related sports medicine)

Medical schools typically do not count these subjects as part of your core offer.

A-Level Grades Required for Medicine

Getting the right subjects is only part of the equation. You also need top grades.

Most UK and international medical schools require:

AAA to AAA, depending on the university
A in Chemistry or Biology* at top-tier institutions

Tip: Always check specific grade requirements on each university’s website.

Entrance Exams for Medicine

Your A-Level subjects also help you perform better on common entrance tests.

1. UCAT (UK Clinical Aptitude Test)

Tests your cognitive abilities, verbal reasoning, and decision-making. Subjects like Maths and Biology can help with preparation.

2. BMAT (BioMedical Admissions Test)

Includes sections on scientific knowledge and essay writing. Having Chemistry and Physics can be a real advantage.

What If You Didn’t Take the Right A-Levels?

If you’re considering medicine but didn’t take the core A-Levels (Biology and Chemistry), don’t panic.

Options include:

Taking a foundation/pre-med year

Some universities offer foundation years for students with non-science A-Levels.

Graduate Entry Medicine

Apply after completing a science-related undergraduate degree.

Access to Medicine Courses

Especially available in the UK, these are designed for mature students or those changing careers.

How to Choose Between Two Subjects?

If you're torn between two subjects (e.g., Physics vs Psychology), consider:

Which subject do you enjoy more?
Which will you likely score higher in?
Which aligns better with your future specialization (e.g., psychiatry vs surgery)?

Remember: A strong grade in a slightly less preferred subject is better than a poor grade in a recommended one.

Final Checklist: Choosing Your A-Levels for Medicine

Here’s a simple checklist to ensure you're on the right path:

Biology

Chemistry

One other subject: Maths, Physics, Psychology, or Further Maths

Target grades: A or A*

Avoid low-rigour A-Levels

Research your chosen universities early

Prepare for entrance exams like UCAT or BMAT

Stay passionate about healthcare and science

Conclusion

Choosing the right A-Levels for medicine is one of the most important decisions in your academic journey. Always prioritize Biology and Chemistry, and carefully consider your third subject based on your strengths and interests. With the right subjects and grades, you’ll be well on your way to securing a place at a top medical school.

Start planning now, stay focused, and give yourself the best chance of becoming a future doctor.
